Versinetic will launch two controller boards intended to simplify the design of single and dual-socket AC electric vehicle chargers at EV Charge Live in Birmingham. The CongaEEL and MinnoRay boards allow two charging sockets to operate through one controller, reducing the separate hardware required in a charger build. Designed for charge point original equipment manufacturers and charge point operators, the products combine power, safety and communications functions across paired boards. Both will be displayed at stand EV38 during the event at the NEC from 22 to 24 September 2026.
Integrated Charger Architecture
Versinetic’s latest product pair addresses a practical engineering consideration for AC charging equipment manufacturers: reducing the number of components that must be sourced, wired and tested independently. Rather than beginning a charger design with dozens of standalone parts, OEMs can use boards designed to operate together from the outset.
CongaEEL is the company’s integrated power controller board for public and commercial AC charging. It incorporates the three-phase mains contactor, onboard RDC-DD, current measurement and ISO 15118 interface on one IEC 61851-compliant board. The board can stack with either MinnoRay or Versinetic’s MantaRay controller board.
Two CongaEEL boards can pair with a single controller in a dual-socket charger configuration. This arrangement gives manufacturers a route to reduce controller hardware while retaining separate socket capability, an appealing proposition for commercial charging installations where equipment cost and assembly efficiency remain important considerations.
Communications In A Compact Board
MinnoRay is positioned as a compact communications and controller board for cost-sensitive charger applications. Its connectivity package combines 10/100 Ethernet, an LTE Cat 1 bis modem, Wi-Fi and Bluetooth on one board, while its OCPP 1.6 compliance supports communication with charge point management systems.
In the paired design, MinnoRay manages communications and CongaEEL handles power and safety functions. The latter also provides the ISO 15118 interface used for Plug and Charge capability. Bringing these responsibilities together in a defined board architecture can help engineering teams avoid building every element of a charger control system from scratch.
The two products support single or dual-socket, three-phase AC charger designs. Versinetic says the approach can reduce the assembly, wiring and compliance testing required when manufacturers develop systems from individual components.
Dunstan Power, Managing Director at Versinetic, said:
“An EV charger is built from dozens of separate parts today, each sourced, wired and tested on its own. CongaEEL and MinnoRay let a manufacturer start from two boards that are already engineered to work together, so the integration work is done before the design even reaches the bench, said Dunstan Power, Managing Director at Versinetic.
Options For Charger Manufacturers
For OEMs, a controller choice that reflects the intended charger specification may be particularly useful across a varied product portfolio. MinnoRay expands Versinetic’s controller offering alongside MantaRay, enabling manufacturers to select an option suited to the requirements of a particular build.
MinnoRay is available directly from Versinetic and can also be licensed to high-volume manufacturers incorporating it into their own charger designs. That route gives manufacturers flexibility in how they adopt the controller architecture within their production plans.
Dunstan Power, Managing Director at Versinetic, continued:
“We’re hearing the same thing from OEMs and CPOs across the market,” continues Power. “They want a connected, compliant charger without carrying the cost of features they don’t need. MinnoRay gives them that option alongside MantaRay, so the choice depends on the build, rather than what we happen to offer.”
A Focus On Charge Point Engineering
Versinetic brings fourteen years of charge point engineering experience to the new boards, with its early work including the control system for charge posts used during the London 2012 Olympic Games. The company develops embedded electronics and software for AC EV charging equipment, supplying charge controller boards, load-balancing hardware and charging software.
The company also provides bespoke charger design work for projects with more specific technical requirements. Its latest launches demonstrate how established charger engineering can be packaged into modular products that make development more accessible for manufacturers and operators seeking efficient routes to market.
Visitors to EV Charge Live can see CongaEEL and MinnoRay at stand EV38 and discuss single or dual-socket charger builds with Versinetic’s engineering consultants. As AC charging infrastructure continues to be specified across public, commercial and workplace settings, component integration offers a credible route to lower-complexity charger development.
